<a name='Perl 6 Summary for 2005-01-31 through 2004-02-8'></a><h1>Perl 6 Summary for 2005-01-31 through 2004-02-8</h1>
<p>All~</p>
<p>Welcome to yet another summary in which I will undoubtedly confuse to homophones.  Probably more than a few this week as I am a little tired.  But perhaps the alien on my window or the vampire on my monitor will help straighten it all out.</p>
<a name='Perl 6 Language'></a><h2>Perl 6 Language</h2>
<a name='autothreading generalization'></a><h3>autothreading generalization</h3>
<p>Luke Palmer's thread about auto-threading seems to have wound down without much resolution, or at the very least without a syntax that I like.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/f64bc3b208a5cd06/fbc0152bfcef5d9b?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#fbc0152bfcef5d9b</p>
<a name='Featherweight Perl6'></a><h3>Featherweight Perl6</h3>
<p>Autrijus Tang introduced Featherweight Perl6, a side-effect-free subset of Perl6.  FP6 is the first step on a journey for Pugs to conquer the world.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/5e4a1efa105db3c2/b1254f644f628355?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#b1254f644f628355</p>
<a name='Value Types vs Implementation Types'></a><h3>Value Types vs Implementation Types</h3>
<p>Autrijus Tang in his work on FP6 became confused by types.  He asked some questions about Types on perl 6 language and was apparently told to go to perl 6 compilers.  From perl 6 compilers, he was told he should really be on perl 6 language.  Sorry for the run around, the proper place for questions about language semantics is perl 6 language as he originally posted.  Eventually all of that was settled and he even got his question answered.</p>

<a name='Logic Programming in Perl 6'></a><h3>Logic Programming in Perl 6</h3>
<p>Ovid asked what logic programming in perl 6 would look like.  No answer yet, but I suppose I can pick the low hanging fruit:  as a limiting case you could always back out the entire perl 6 grammar and insert that of prolog.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/05e3e963af533c66/556d922352badfe2?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#556d922352badfe2</p>
<a name='the leaning tower of numbers'></a><h3>the leaning tower of numbers</h3>
<p>Autrijus Tang asked what sort of number tower Perl6 had.  He was planning (and implemented) that of Scheme until he gets an answer.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/c17f00f2dfaaae75/c058273872964662?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#c058273872964662</p>
<a name='some quick questions'></a><h3>some quick questions</h3>
<p>Autrijus Tang asked a few questions about operators in specific contexts.  He got a few answers, although I don't think he got them all.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/9104105fcb8ce308/0f34dd175d56e95b?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#0f34dd175d56e95b</p>
<a name='getopt::signature'></a><h3>getopt::signature</h3>
<p>Juerd wants to be able to give his script a general signature which magically parses command line arguments.  Many people thought it was a cool idea that should be provided as a module rather than in the core.  This led to talk about creating a signature object which could be passed to this module so that it doesn't need macros.  Sounds good to me.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/d013231e60281c54/0f56b04b11e61c4b?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#0f56b04b11e61c4b</p>
<a name='S03 inconsistency'></a><h3>S03 inconsistency</h3>
<p>Juerd found a knit to pick.  No comment about whether to pick the first or second option though...</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/1e04c404b2312e4f/5bb4241195ceba2d?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#5bb4241195ceba2d</p>
<a name='regex precedence'></a><h3>regex precedence</h3>
<p>Nicholas Clark wondered about adding a little operator precedence to regexes so that people could avoid a few common problems.  Sounds like a good idea to me...</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/d7a6bbcadb6503d2/a01fa36ef116dd02?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#a01fa36ef116dd02</p>
<a name='pipe dreams'></a><h3>pipe dreams</h3>
<p>Juerd wondered if he could mix = and ==&gt; in a sane way.  The answer appears to be no.  Once you bring in ==&gt; you should stick with it.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/c5bb4a6d5a6e6ed5/40ff805393136f1f?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#40ff805393136f1f</p>
<a name='4 &lt; $x &lt; 2 == true?!?'></a><h3>4 &lt; $x &lt; 2 == true?!?</h3>
<p>Autrijus Tang wondered how junctions and chained comparators worked.  He found that under certain semantics, one can receive very troubling answers.  Larry agreed with Autrijus that the unintuitive semantics should be avoided.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.language/browse_frm/thread/9b872c9ed83288e0/dee3c5ceaccf1882?_done=/group/perl.perl6.language?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#dee3c5ceaccf1882</p>
<a name='Perl 6 Compilers'></a><h2>Perl 6 Compilers</h2>
<a name='Pugs 6.0.0'></a><h3>Pugs 6.0.0</h3>
<p>Autrijus Tang released Pugs 6.0.0.  It has many cool features and was created in only 6 days.  A testament to the power of Haskel or the caffeine intake of Autrijus.  (Although to be fair he skipped more version numbers then Java did in its jump to 5.0...)</p>

<a name='gdbmhash warning'></a><h3>gdbmhash warning</h3>
<p>Bernhard Schmalhofer fix a problem where gdbmhash could make configure produce a warning.  Leo applied it.</p>

<a name='PyNCI'></a><h3>PyNCI</h3>
<p>Sam and Leo worked out the correct way to create NCI methods for Python.  Leo ended by proposing a table to assist Parrot based on the current language, no answer to that idea...</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.internals/browse_frm/thread/2853a00850a9b11c/481de9502b44540e?_done=/group/perl.perl6.internals?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#481de9502b44540e</p>
<a name='makefile cleanup'></a><h3>makefile cleanup</h3>
<p>Bernhard Schmalhofer cleaned up some of the makefiles and configure system.  Leo applied the patch.</p>

<a name='ParrotIOLayer* const or not'></a><h3>ParrotIOLayer* const or not</h3>
<p>François Perrad provided a patch making the ParrotIOLayer* const in the API.  Leo applied it, but  Melvin warned that while this may be safe now, the API intended to allow mutability.  I think for the moment it is still in though...</p>

<a name='FreeBSD build problems'></a><h3>FreeBSD build problems</h3>
<p>Will Coleda found a build problem for parrot on FreeBSD.  Adriano Ferreira provided a work around, but the build system needs to be smarter too.  On a side note, I want a picture of the BSD daemon (pitch fork included) with a pirate hat, an eye patch, and a parrot on its shoulder.</p>
<p><a href='http://groups-beta.google.com/group/perl.perl6.internals/browse_frm/thread/0249207572737092/a8c5db31dbd75085?_done=/group/perl.perl6.internals?' target='_blank'>groups-beta.google.com</a>&amp;_doneTitle=Back+to+topics&amp;_doneTitle=Back&amp;&amp;d#a8c5db31dbd75085</p>
<a name='gmake requirement?'></a><h3>gmake requirement?</h3>
<p>There was some confusion about what does and does not require gmake on FreeBSD.  IMCC does not.  ICU does.  Fortunately, with Dan's string stuff ICU will become optional and so we won't require it.</p>

<a name='locate_runtime_file with absolute paths'></a><h3>locate_runtime_file with absolute paths</h3>
<p>Jeff Horwitz notices that Parrot_locate_runtime_file could segfault when playing with an absolute path.  He put some work in to fix it.</p>

<a name='expected vpm.imc output error'></a><h3>expected vpm.imc output error</h3>
<p>Bernhard Schmalhofer fixed a failing benchmark test which just had slightly wrong output expectations.  chromatic (whose uncapitalized name does not bother me) applied the patch.</p>

<a name='Parrot 0.1.2?'></a><h3>Parrot 0.1.2?</h3>
<p>Will Coleda wondered if the time for Parrot 0.1.2 was growing close.  Leo pointed out some things that need to be fixed.  Honestly, the real impetement is that we do not yet have a cool code name for it.  I suggest kiwi, because everyone knows they really want to be parrots.</p>
